Relative expression of DNA repair transcripts by RT-qPCR in Col0, ddm1 (ddm1_093009 line) and ros1 (ros1_135293 line). Levels of UVR2, UVR3, UVR7, UVH1, UVH6, and OGG1 were assayed in arabidopsis plants that were irradiated with UV-B for 4 h (UV-B) or were kept under control conditions without UV-B (control, C). Expression values are relative to the values in Col0 plants under control conditions in the absence of UV-B. The CPK3 transcript was used as a control. Data show mean values ± S.E.M. of at least three independent experiments.
